Revolution and revolutionary and revolutionise have of course also come to be used, outside of political contexts, to indicate fundamental changes, or fundamentally new developments, in a very wide range of activities. It can seem curious to read of ‘a revolution in shopping habits’ or of the ‘revolution in transport’ and of course there are cases when this is simply the language of publicity to describe some ‘dynamic’ new product. But in some ways this is at least no more strange than the association of revolution with VIOLENCE, since one of the crucial tendencies of the word was simply towards important or fundamental change. Once the factory system and the new technology of the late eighteenth century and early nineteenth century had been called, by analogy with the French Revolution, the INDUSTRIAL Revolution, one basis for description of new institutions and new technologies as revolutionary had been laid.
(Williams 1976:229-30; emphasis in original)
Revolution, in whatever sense it is used, implies movement, and in these developed usages, that means movement through time. The concept of the ‘Information Revolution’ is therefore in essence historical.
